After reading these messages I had to write to try to balance the situation a little.
Korea is NOT all bad guys!
I've been here over 6 months & no problems with pay at all. Always on time. I also know many people who are into their second year in Korea & have never had any problems with their school, pay etc ( just the usual problems of a lousy schedule maybe!) Everyone at my school is great, manager, teachers, even students! So just do your research before you come & everything should be fine!!
